Microstructures Formed by Charge Ordering Transition in Pr0.55Ca0.45MnO3 and Nd0.5Sr0.5MnO3

Abstract

We have made crystallographic analysis for microstructures formed by charge ordering transitions in Pr0.55Ca0.45MnO3 and Nd0.5Sr0.5MnO3. From the results, it was found that all interfaces between crystallographic domains of Pr0.55Ca0.45MnO3 are {101}CO ( CO represents a charge ordered phase)
twinning planes and that most of interfaces between crystallographic domains of Nd0.5Sr0.5MnO3 are {112}CO twinning planes. These twinning planes correspond to {110} planes in simple cubic perovskite structure.
